Introduction
Titian Service supported an offshore pigging campaign where the IK Trax EMRx receiver and EMTx20 transmitter were used for pig tracking after a pig became lodged in the pipeline. With the in situ signal system not functioning and offshore conditions creating interference, IK Trax equipment provided clear, consistent detection that enabled the team to confirm the pig’s position and safely retrieve it.
Challenges
The pig was launched through a 14 inch gas pipeline around 3.2 km in length. After launch, pressure and noise readings suggested it had reached the receiver. However, when the barrel was opened, the pig was not there.
With the original signal system out of action and offshore vibrations creating background noise, pig tracking became more difficult. The pipe wall thickness was 23.83 and this was taken into account.
Solutions
Titian used IK Trax EMRx receivers at both the launcher and receiver for pig tracking. When the pig failed to arrive, scanning was carried out along the riser and receiver area using the EMRx, alongside an EMTx20 transmitter installed in the pig.
Although false signals were encountered due to background noise, one location showed a consistent, localised transmission. The pig was confirmed to be stuck near a valve, where a mechanical obstruction had occurred. Once corrected, the pig was released and safely recovered.
Conclusion
This project demonstrated the reliability of IK Trax pig tracking solutions by using the EMRx receiver and EMTx20 transmitter in offshore pigging operations. When other systems were unavailable, IK Trax provided the clear, consistent tracking needed to safely complete the campaign.
Result
The EMRx and EMTx20 worked together to deliver a steady, reliable signal that helped the team confidently locate the pig. Detection through the pipe wall in an offshore setting with environmental interference was still possible after six days. The operation was completed without the need for contingency measures, and the IK Trax system supported safe decision making throughout.
